' This invention relates to new and useful improvements in chimney cleaners and the main object of my invention is the provision '{of a device of this character includingmeans for retaining the cleaning members ina retracted position While being supported in .the chimney and means for releasing i the brushes to an expanded position for engag' ing the walls of the chimney when the device has been moved into contact with the bottom of the chimney.

Another object of my invention is the provision of 1 'a chimney cleaner including a *frame'upon which 'I mount a plurality of cleaning-members operatively arranged in a projecting osition so thatthey will; engage the interior of chimneys'of various sizes 'to- 5 gether with means for retaining the cleaning members in acontracted o'r inoperative 'ber, parts thereof being illustrated in cross section.

Fig. 1 is a transversesection. on the line 4-4 of Fig. 1, and

Fig. 5 is a detail elevation of the trip membroken away and In the construction of my improved chimney cleaner, I provide a top frame 1 which is rectangular in form as clearly illustrated in Figure 2 and attached to each side of this frame are the spaced resilient strips 2 which form supporting arms for the cleaning mem-.

bers 3. v r I Arranged in spaced relation with the frame 1 is a second frame 4 somewhat larger than the frame 1 and the strips .2 are riveted or otherwise'secured to thisframe 4 as at 5 thus producing a spreading of thesupporting arms for the cleaning members whereby to cause the lower ends thereof to be disposed in ajlongltudlnal plane some other objects in View, cleaning members as the invention consists in the novel features." of construction, the combination and an rangement of parts hereinafter more fully what beyond the outer sides 'of the frames 1 and 4. 7 The cleaning members 3 may be secured. to the outer ends6 of the arms 2 in any suit-. able manner but the cleaning members 3 are as is clearly illustrated in the drawings. The cleaning members are retained in a closed or inoperative position by means of a .trip member whlch 1nclud'es a centrally dispreferably provided with a back portion 7 i I posed rod 8 having its lower endthreaded I I as at 9 and positioned upon thi's'rod'fi are the arms 10 which extend at right-angles to each other and. are provided with. 'downturned "ends 11 which engage overthe upper edges of the back portions 7 of the cleaning members for retaining 'them' in 'an' in0pera tive position as shown in'F-ig'. 1.- A stop nut 12 is-mounted upon the rod8andfixed be-. tween the nut 12 and the'body porti'onsof the arms 10 is aicoil spring 13'Which-nor vmally retains the down-turned: ends of the arms 10 in engagement with thebacksof the Y the cleaner is lowered intoa chimney, either the lower end of the rod 8 will engagethe bottom of the chimney or, the ends of the chimney for moving therod 8 upwardly to disengage the down-turned ends 11 'of the arms 10 from the backs 7 offthe'i cleaning members releasing the cleaning members whereby they will spring outwardly toan operative position as shown by dotted lines in Fig. 1. The, cleaning members maythen be moved within the chimney for cleaning the same of soot or debris. V

In order to securely brace/the two frames cross-piece 14 will-engage a support in the,

1 and 4, cross-bars 16 are provided the ends of which areturned over the outer faces of the frames' and riveted or otherwise secured thereto as shown at 17, the rivets which attach the crossbar 16 to the upper frame 1' able meansmay be used for attachment to" the handle 18 whereby to raise and lower the cleaner within the chimney. It will be being also used for attaching the ends of a handle member 18 to the frame.' Any suit- I noted that the upper end of the rod 8 extends thru suitable openings in the crossbar 16 for guiding the rod 8 in its movement.

It will be apparent from the foregoing that I have provided a comparatively simple device for cleaning chimneys and by forming the lowermost frame 4- .somewhat larger than the frame 1, it will cause the outer ends 6 of arms 2 which support the clean ing members 3 to diverge as shown by dotted lines in Fig. 1 to thus bring the cleaning members into yieldable contact with the in ner surfaces of the chimney to assure a proper cleansing of the walls of the chimney. It will, also. be noted in order to facilitate the insertion of the tool within a chimney, the arms and cleaning members may be moved to a converging position as shown in full lines in Fig. 1 and readily released when the device reaches the bottom of the chimney.

lVhile I have shown and described the preferred embodiment of my invention, it will be understood that various changes and alterations may be made without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention,wl1at I claim is:

1. A device of the character described including spaced frame members, resilient arms secured at one end to said frame members and their free ends arranged in diverging relation, cleaning members carried by the free ends of the arms, means detachably engaged with the cleaning members for retaining the arms in a converging relation and means whereby to release said retaining means.

. 2. A device of the character described including spaced frame members, resilient arms attached at one end to said frame members, the free ends of said arms being normally disposed in divergent relation, cleaning members carried by the free ends of the arms, a movable rod supported by the frame members, retaining members carried by the rod, for engaging the cleaning members to retain the arms in converging relation and means whereby to disengage the retaining means from the cleaning members to permit the arms to assume their normal position.

3. A device of the character described includin spaced frame members, one larger to I v than the other, resilient arms having thelr ROLAND R. SCHAEFER.
